Q:We have to develope LED outdoor  Luminaires with maximun 1%  of blue radiance. That is   betwen 300 to 379nm, must be less than 1% of the spectral radiance between 380 and 780 nm.

We tried 2200°K led luminaires  and we obtain between 5 and 7 % instead of 1%. This luminaire could be possible to be used on middle distance to Observatories. But for short distance to Observatories , MUST BE LESS THAN ONE %.

What do you think, how to get that goal?
